BERLIN (Reuters) - If U.S. Republican presidential candidate Donald Trump wins the election in November, it would be problematic for the entire world and encourage copycats in Europe, European Parliament President Martin Schulz told a German magazine.

"Trump is not only a problem for the EU but also for the whole world," Schulz said in an interview with Der Spiegel published online on Thursday.

"If a man who shows off by not having a clue and by saying that specialist knowledge is elitist rubbish ends up in the White House, a critical point will have been reached," said Schulz, a German center-left Social Democrat.

Such a scenario would mean that there is an "obviously irresponsible man" sitting in a position that demands the utmost sense of responsibility, Schulz said.
